CAUTION:
Do not use a power auger since they may enlarge the hole diameter beyond the desired
specification for a properly installed probe. Power augers also tend to bring soil up from
lower depths, coating the sides of the hole, which may have adverse effects on the
measurements.
1. Connect the T-handle (
(p. 8), G) to the auger extension shaft (
A) then connect the shaft to the auger (
(p. 8), D).
2. Use the auger assembly to create a hole with a 5 cm (2 inch) diameter that is approximately
5 cm (2 inch) deeper than the SoilVUE 10 length. The auger is narrow at the tip, so making
the hole 5 cm (2 inch) deeper will ensure the sensor can be fully installed.
CAUTION:
Large gaps between the SoilVUE 10 and the hole bottom can adversely affect the
measurements. The following auger depths allow proper installation, while avoiding
large gaps.
a. Care should be taken to ensure the sides of the hole are even and do not become
tapered with repeated removal of soil.
b. Wet the sides of the hole to reduce the force needed to install the probe. In most
cases, the hole will need to be thoroughly wetted.
CAUTION:
When adding water to the hole, avoid eroding the sides, introducing air gaps. Also
avoid having standing water at the bottom of the hole.
